The question is: how many CPU threads at 100% to decompress at 9GB/sec?
Hint: it can be pretty painful.
Current NVMe standards are limited to PCIex4 which is 7.8GB/sec
And that's why GPU's come in. If that chip was not in the PS5 the PS5 would not be slamming in that box a 16 core ryzen cpu just to waste it on compression, it would simple take the hit on the GPU front and call it a day.
No current x4 or x8 slots are limited towards that speed, SSD's are not limited towards these slots. U can slam them into a x16 slot and u can slam even multiple in there. U need some cpu lanes tho, but hey its perfectly possible. Reason why nobody does it however? u get exactly zero gains other then brag rights because nothing other then video editing makes use of it.
I think linus did some test video about this a while ago, sadly it was riddled with trolls that took great offense as they saw it as a attack on there favorite game station for some reason and tried to shit as best as they could all over it. That's 2020 for you.
The current PC limitation are below:
Limitation currently for PC = 63gbps on the SSD front as u can raid two of them. and about half of that on pci-e 3.0. And that's RAW not compressed. With compression the sky is the limit really.
Unlike AMD fanboys want people to believe intel wasn't trolling when they said they don't see much use in 4.0 at this point and AMD probably agree's with this as i could see them jump on the 5.0 wagon in 2022 in there first products already. Pci-e 4.0 is nothing but a marketing stunt by amd at this point to make there chipsets look more modern while weaker vs the competition. Smart business.
Sadly nobody will tell u that, because they all visit those shitty youtube experts that have no clue themselves and google everything themselves from other tech youtubers. That's why i laugh at these clowns 24/7 whenever they make a youtube video about shit they don't even understand themselves and make complete fools of themselves while they are at it.
Sadly there is always a array of npc drones that will come to their rescue and take their diarree and spread it all over the net like its some kind of fact because he said so and has a bunch of viewers so it must be true right? lol
